  • Method and apparatus of cleaning residual anodes employed for fused-salt electrolysis
    Patent number: 4585538
    Abstract: For cleaning purposes, residual anodes obtained in fused-salt electrolysis are rotated and exposed to a flow of striker bodies which knock the bath material off the residual anode. To this end it is particularly recommended to pivot the residual anode from a vertically suspended position to an inclined pivoted position, in which free-falling striker bodies strike the anode with sufficient force and clean the same.
